"The Swiss Department of Foreign Affairs has called on Russia to immediately end illegal activities on Swiss soil or against Swiss targets," reads the statement.

In September, it became known that two Russian spies were detained in the Netherlands. They intended to obtain data from a chemical laboratory in Spiez (Switzerland) involved in investigation of chemical attacks in Syria and Great Britain, testing chemical and biological weapons, and studying nerve agents such as Novichok.

Meanwhile, Swiss prosecutors said that the two Russian spies detained in the Netherlands are suspected of the attempt to commit cyberattacks against the offices of the World Anti-Doping Agency (WADA) in Switzerland.

German media reported earlier that Russian hackers had targeted the Swiss laboratory which analyzed samples from the March poisoning of former Russian spy Sergei Skripal and his daughter in England.

The German Federal Office for the Protection of the Constitution said Russia's special services were probably behind the attacks.
